Problem started several days ago when I turned my camera on. Monitor and viewfinder were flickering so much that I couldn't see the image. I played around with the controls (power on-off, zoom in-out, etc) until I thought the problem was suddenly fixed. Unfortunately it was not fixed. There is random unpredictable flickering which shows on the photos I take. Your help will be appreciated.
I don't have a solution, but do have the same problem. Mine is cleared by switching the camera off and back on again. Also the problem doesn't appear for long, clearing itself, on some ocassions. The problem stated when I was in a hotter climate, about 35degree celcius.
I bought my camera about 3 months after release, I'd be interested to know the age of yours and if this is a common problem. Have you had your camera fixed?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
Problem now solved. I switched the camera on and off a few times and took several test photos. After a few minutes the problem resolved itself. I suspect the cause was condensation, but cannot be sure.
Monitor flickering can be one or several problems. Depending upon the age of the unit and value, you should decide weather to repair it or replace it.! More than likely, it is a problem in your power supply. The capacitors in the supply will leak and most often crown. If when you start unit after sitting for a while, it shows good and then after a few minutes it starts flickering, you can bet it is one or several capacitors in the supply. This monitor is a 17 inch and not really worth the time and investment to repair, unless you have the technical skills to remove and replace electronic components.
This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:
I have a envision professional series and I love it, but I will get to the point.
I recent ly received a Envision EN9410e monitor, had the same problem (flickering screen then turned on, then off then on then blank). The problem is bad capacitors. There are 7 electrolytic capXon capacitors that will need to be replaced. You should see if the caps are bulging or leaking, if so replace. As known by many replace with the same capacitance and voltage. There are a few incidences that the capacitors where replaced and the problem wasn’t solved; this is because the cap problem wasn’t taken care of and damage occurred to another part of the monitor. The back light is a Royer oscillator (cool things) and it uses two smd mosfet transistors. They are on the green side of the circuit board near a big control chip (they each look like a off rectangle black square with eight pins) you need to see if there is any carbon or chard residue between the pins or burning smell from them, if there is you need to remove the transistor and do some board repair then ether put a new transistor or try the old one. No offence to the people at Envision but not smart putting the drain, gate and source so close to each other under the chip where there is such high voltage! Hope this helps.
